ECCENTRIC Filed April 25, 1930 IN VEN FEW Mum/ML ZAMLE y ATTORNEYPatented May 2, 1933 WILLIAM It. LAMLEY, F LYNWOOD, CALIFORNIA EGCENTRIGApplication filed April 25,

This invention relates to an eccentric particularly useful upon mudclassifiers and the prime object of my invention is to provide aneccentric which can be quickly and easily repaired, and which is sturdyin construction so that the parts thereof will not readily break norwear out.

Other objects, advantages, and features of invention may appear from theaccom- W panying drawing, the subjoined detailed description, and theappended claim.

In the drawing Figure 1 is a side view of the eccentric with the coverplates removed.

Figure 2 is an end view of the eccentric housing.

Figure 3 is a transverse, sectional View of the eccentric runner.

Figure 4 is a side elevation of one cover plate.

Figure 5 is an end view of the adjusting collar.

Figure 6 is a side elevation of the same.

The eccentric which I employ is shown in Figures 1 to 6 inclusive, andincludes a housing 22. Ears 23-23 extend from either side of the housingand the connecting rods 21 are pivotally secured thereto. A runner 24 isrotatably mounted in the housing 22 upon a plurality of bearing segments25.

These bearing segments are set in grooves in the housing 22, and bearagainst the out.-

er surface of the runner 24. Openings 26 are provided through theperiphery of the housing 22, and communicate with the segments 25. Thepurpose of these openings is to permit the molten metal to be pouredtherethrough to form the bearing segments when one or more are destroyedor become worn.

The runner 24 is used as a babbit form when pouring the segments. Itwill be evident that the segments can be quickly and easily poured andare relatively inexpensive. The runner 24': is provided with a centralelongated opening 27, and two parallel ad- 1 justing slots 28-28, one oneither side of the opening 27. An adjusting collar 29 is secured to theshaft 10, and said collar is provided with a flange 30. Bolts extend1930. Serial No. 447,214.

through the flange and through the adjusting slots 28 for the purpose ofadjusting the position of the collar on the runner 24. Thus theeccentricity of the runner can be regulated as desired.

A cover plate 31 is bolted to the housing 22 forming an assembly, themoving parts of which are enclosed and are not susceptible to greatwear, the cover plate also retains the lubricant in the eccentric andprevents oil from dropping into the classifier.

Having described my invention, I claim:

An eccentric for mud classifiers and the like, comprising a housing,ears on the housing to which connecting rods arepivotally secured, arunner, a plurality of arcuate bearing segments secured in the housingand bearing against the runner, said runner having an elongated openingtherein, and a pair of elongated adjusting slots, a collar secured tothe drive shaft flanges on the collar, bolts extendin through theflanges and through said ad usting slots whereby the collar iseccentrically mounted on the runner, and a cover plate secured to thehousing.

In testimony whereof, I aifix my signature.

WILLIAM L. LAMLEY.
